In SharePoint JSOM, following is the correct way to set the lookup column in list:

var lkfieldsomthing = new SP.FieldLookupValue();  
current.set_item('InternalNameOfLookupField', lkfieldsomthing);


  1. Lookup_ID : The unique, SharePoint default ID of the list item from where your are referencing your lookup(Source/Provider List).

  2. InternalNameOfLookupField : Internal name of lookup field in your Destination/Consumer list. You can get the internal name of your lookup column by following this article: How to find the Internal name of columns in SharePoint Online?

  • Free text will not get added in the lookup field. To set the lookup field you need to save the ID of the list item from where your are referencing your lookup(Source/Provider List). Feb 11, 2019 at 14:58

  • You cannot use the free text for lookup columns. You need to use the select tag and bind the list items IDs as a value to each option in your select tag. Feb 11, 2019 at 15:17
